FLUE- STOP.

SPECIFICATION forming part of Letters Patent No.324.,216, dated August 1l, 1885.

(No model.)

To @ZZ whom it 'may concern:

Be it known that I, GEORGE BOOTH, a citizen of the United States, residing `at Phila1 delphia, Pennsylvania, have invented new and useful Improvements in Flue-Stops, of which the following is a speciiication.

This invention relates to improvements in what are known as lue-stops"-that is, an annular disk of metal for covering and concealing the ordinary opening provided for the insertion of a stove-pipe into a chimney or smoke-flue.

It is very desirable to provide a fine-stop which can be cheaply manufactured and be adapted. to lues of varying size or diameter, and at the same time be an ornamental adjunct and capable of being shipped in large quantities with economy in space. n

Various contrivances for covering tlue-open ings have been heretofore manufactured, among which is a combined ventilator and flue-stop, composed of a dished plate of metal having a perforated valved rim, and centrally struck up to form a series of lugs, between each pair of which is secured one end of a curved spring-finger, the other or free ends of a series of spring-fingers so attached being adapted to enter and bind against the sides of the fine-opening for the purpose of confining the dished plate over the latter. This contrivance is in some respects desirable, but is comparatively expensive of manufacture incident to its va-lved construction and the necessity of providing a series of separate spring-fingers, each of which must be independently attached. Besides, the nature of the spring-fingers is such as to restrict, to a considerable extent, the application ofthe device to fines of greatlyvarying size or diameter.

. The object of my invention is to provide a flue-stop with a device of novel, economical, and efficient construction, whereby the fluestop can be conveniently used for fines of greatly-varying size or diameter to admit of a wider range in the application of the stop.

The invention also has for its object to pro- .vide a iiue-stop with a single securing-spring,

which will perform the function of a series of spring-ngers heretofore employed,and which will admit of the stop being applied to iiues varying greatly in size or diameter.

The invention also has for its object to provide for so packing the parts of the ilue-stop in a flat condition that a large number can be shipped within a limited space, thereby utilizing room in transportation.

To such ends my invention consists in the construction and combination of devices, hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a perspective view, looking at the rear side ofthe stop-flue; Fig. 2, asimilar view showing almodication of the invention; Fig. 3, a transverse sectional view of Fig. l, showing the parts detached andin the position they occupy when packed for shipment.

In order to enable those skilled in the art to make and use my invention Iwill now describe the same, reference being made to the drawings, where the numeral l indicates an approximately flat annular disk of metal,formed near its margin, with a circular bead, 2, to constitute a recess for receiving an annular sheet of paper or other material, 3, which in practice is furnished withv an ornamental exposed face. This face may be ornamented in any desired manner-as, for example, by printing or otherwise producing in colors thereon a picture or design of any character suited for the occasion. The central portion of the disk is provided with two parallel incisions or slits andthe metal intermediate the incisions is struck up or pressed out to form a loop, 4; but while I prefer this manner of making the loop for the purpose of economy and strength, I may provide the loop by soldering the ends of a separate strip of metal to the disk,as shown in Fig. 2. The loop forms a retainer for attaching to the disk a ring, 5, of metal, having a division, G, so that it can be conveniently withdrawn from the loop or engaged therewith by inserting one end of the division under the loop, and drawing it through sufficiently to place the ring in the proper position. The ring is preferably made of sheet metal--such as hoop-iron-and is sufficiently flexible and elastic to permit it to be expanded or contracted to accommodate it to the size of the flue to which the stop is to be applied. The nature ofthe ring is preferably such that when expanded or contracted to fit the flne-openingit IOO willhave suillcient resiliency to aet as a spring, so that when inserted in the flue the periphery of the ring will bind against the opposite sides of the flue-opening and thereby confine the disk over the latter for closing and concealing the saule. \Vheu the metal ofthe disk is slitted and struck up to form the loop, the opening lnadc through the disk thereby will be covered and concealed by the disk 3, of paper or other material; but the paper disk is not necessary to perform this function where the loop is formed by a separalirly-attached metal strap, as in Fig. 2.

By attaching the split ordivided ring to the center of the disk intermediate the extremities of such division, it will be obvious that the ring can be'conveniently expanded or contracted to suit the conditions required, and that the binding points of contact are, with the sides of the line-opening, the periphery ofthe ring.

Having thus described my invention, what I claim isl.. Aline-stop consisting of ailattened disk,

l, having a centrally attached loop, 4, and a spring-ring, 5, loosely passing through and slidable in the loop, and provided with a division, 6, forming free and disconnected ends to the ring, whereby the ring can be slid from the loop and laid edgewise on the disk, as and for the purposes set forth.

2. A llucstop consisting of a disk formed integral with a central loop and a surrounding bead adjacent to the margin to constitute a seat, an exterior imperforate disk secured in the seat with its edge against the surrounding bead, and the spring-ring secured in the loop, substantially as described.

In testimony whereof I adix my signature in presence of two witnesses.
